' s clams. (CI. 12943) invention relates to improvements in nee-- d-le frames for gauze weavinglooms.

Needle frames used in gauze weaving looms are liable to produce defects in the fabric if, and

when, the thickness of the warp yarn exceeds the normal thickness of the warp yarn used. in the production of gauze, because the doup needles cannot bear closely against the dents of the frame due to the excessive thickness of the y rn therebetween.

According to the presentinvention, the eyelets in the free end portions of the doup needles are located exteriorly of the plane of the dents, i. e., spaced forwardly thereof, so that the elasticity of the yarn permits the free ends of the needles to bearagainst the dents. The free ends of the needles are therefore formed with forward bends and the eyelets are located at the bends of the needles so as to be in a line front dents.

The features of the invention are shown in the accompanying drawings forming a part of this application.

In the drawings:

Fig. 1 is a fragmentary front view of a needle frame for gauze weaving looms in which the features of the invention are shown in an illusof the the tongues if: of the needles it are pressed against the adlacent dents i3. 'It will be noted that the elasticity of the yarns Y extending through the eyelets IS in front of the dents i3, and below the tongues of the needles, permits these yarns to be pressed against the adjacent dents I3 so as to leave ample room for passage of the crossing yarns Z. The yarns Y are therefore not pressed between the tips of the needles i I and the dents i3, as in previously known needle 7 frames.

It is to be understood that the invention is not restricted to the particular form of bend lllustrated for the needles ll. What is claimed is: f 2

In a needle frame for weaving looms including a row of spaced 'dents extending between cross-bars of the frame, and doup needles alternating with the dents of the frame, the improve- Fig. 2 is a side view of the mine shown in Fig. 3 is an enlarged fragmentary sectional plan view taken on the line III-III of Fig. 1 and illustrating the action of the needles in connection with the position of the yarns and dents of the frame.

Referring to Figs. 1 and 2 of the drawings, ll indicates the top cross-bar of the needle frame, H the bottom cross-bar and I! one side of the The dents of the frame are indicated H, and I 4 indicates the doup needles which alternate with the dents II. In the structure as shown. the dents II are flat elements mounted parallel to each other in the usualmanner-between the cross-bars ll and H. while the doup needles, also flat elements, have their lower ends fixed and mounted in the cross-bar ll, so that they alternate between the dents ll.

The free ends of each needle I! as shown in Fig. 2 is formed with a forward bend or tongue II, the tip of which projects between adjacent dents ment which comprises doup needles extending from one of the cross-bars and each terminating with a, free end intermediate the cross-bars, the free end portion of each needle having an eyelet to one side'of the row of dents, the eyelets of the needles being in register in a line to one side of the row of dents, and each needle having an ofiset tip end extending between adjacent den-ts and adapted to eng ge the adjacent sides thereof beyond and verticallyspaced from the position of the eyelet in the needle, whereby a yarn'extending through the eyelet and between adiacent dents is free of and in substantially the same vertical plane as the tip of the needle.-

dents to pass around an edge of the needle and I8. Each needle is provided with an eyelet ll at its bend, the eyelets being located exteriorly of the plane of the frame or'dents ll. In other words. the registering eyelets i. are located in the bends ll of the needles It, so as to be in line in front of the dents ll of the needle frame,

Fig. 3 illustrates the position of the rams when in front of an adjacent dent when the tip of the needle is in contact with said dent.
